Slow-mo metal scraping metal has to be the third worst annoying sound in the world.

Turtle noses.

No Casey Jones.

Foot clan masks look dumb (opinion, of course), are less ninjas and more just armed thugs.

Shredder's swiss-knife arms look pretty goofy when all out.

Shredder's suit seems too high tech compared to everything else in the movie.

April doesn't make a move that would cause her to seem a lot less crazy to her boss at one point. I mean, whatever, it works for the plot, but it seems like they should have done at least a quick brush off of it or something.

Opinion

Of all the Michael Bay does your childhood movies, this is the one I did not feel bad about spending money on. The overall plot of the movie can be pretty serious, but the turtles themselves do a wonderful job of bringing humor to situations, and there's more than a few times the crowd at the theater was laughing. Add to that some cool fight scenes, a drop-dead gorgeous Shredder suit, and a bunch of little details like lines said and it comes off to be a rather enjoyable experience.

For opinions on the Old movies versus the New, read the next bit. I'd do it versus comics, but I have not read those, and quite honestly my memory of the old cartoon is much too foggy to be used for any comparison purposes. Let's just leave it at: I feel they did a pretty good job at capturing what could be considered the feel of Ninja Turtles as I remember it.
